Abstract

The present invention provides an extension arm apparatus (100) with angled clevis operation to provide enhanced mechanical leverage. The clevis (146) adjusts along a path angled relative to an axis of an endcap (118) of the apparatus (100), which significantly boosts performance and can reduce the size of the apparatus (100). Upper and lower channels (104, 106) of the apparatus (100) taper from a first width (W1) to a second width (W2), providing a sleek and functional apparatus (100) that can be used with heavy monitors, displays or other user equipment (302). When a forearm extension (110) is attached to an endcap (108) of the apparatus (100), an interlocking washer (258) and shaft (264) configuration prevents the forearm extension-endcap connection from loosening during operation.
